I've found a query that returns questions from users with a certain minimum reputation:
select top 20 p.id as [Post Link], p.score, p.viewcount, p.answercount, p.tags,
u.reputation
from posts p, users u
where p.owneruserid = u.id
and u.reputation >= 1000
and p.deletiondate is null
and p.tags like '%python%'
order by p.creationdate desc
but I'd like to further filter the resultset by users who have answered more questions than they have asked - or alternatively, have a minimum reputation from answers only. Is this possible?
